!Sylevel shows item levels as a overlay over items in the paperdoll frame and in the bags. sadly it doesnt work for bags with a bag addon installed.
For ElvUI and Bagnon there are addons that allow !Sylevel to be shown. Is there any way i can make !Sylevel work with Combuctor too? I contacted the author of !Sylevel (he wrote the plugins too) with no answer so far
